Missing dependency "keyring: None (NoK)" in Spyder 4

Question

Having recently upgraded to Spyder 4 on Anaconda, I am getting this Error message:

I am aware of this question, but that relates to Spyder 3, and is not working in my case.

My system runs on Linux Mint 19 with Anaconda Navigator 1.9.7, Spyder 4.0.0 and Python 2.7.16 64-bit.

Answer 1

(Spyder maintainer here) This is an error in the way we're registering keyring as a dependency because we don't really require it on Linux and Python 2.

It'll be fixed in our next version (4.0.1) to be release shortly.
